Title: A combustion model with unbounded thermal conductivity and reactant diffusivity in non-smooth domains Author: Sikiru Adigun Sanni (Univ. of Uyo, Nigeria) Abstract: In this article, we present a strongly coupled quasilinear parabolic combustion model with unbounded thermal conductivity and reactant diffusivity in arbitrary non-smooth domains. A priori estimates are obtained, and the existence of a unique global strong solution is proved using a Banach fixed point theorem. Submitted June 25, 2008. Published May 04, 2009.
